INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Aspects of the present disclosure are directed to a methods and systems operable by a network entity for wireless communication, that includes determining that User Equipment (UE) is in idle mode and receiving eMBMS (evolved Multimedia Broadcast and Multicast Service); and based on the determining, activating a power optimization procedure in order to reduce power consumption of the UE. Examples of a power optimization procedures include a single or multi-level hardware shut down procedure, lowering the clock rate of hardware, and shutting down a communication bus during periods of non-use. ## Claims ### Claim 1 A method operable by a network entity for wireless communication, comprising: determining that a User Equipment (UE) is in idle mode and receiving eMBMS (evolved Multimedia Broadcast and Multicast Service); and based on said determining, activating a power optimization procedure in order to reduce power consumption of the UE. ### Claim 2 (depends on 1) The method of claim 1 wherein the power optimization procedure is at least one of: a deep sleep; a light sleep; or a micro sleep. ### Claim 3 (depends on 1) The method of claim 1 wherein the power optimization procedure is a multiple level hardware shut down comprising: a deep sleep; a light sleep; and a micro sleep. ### Claim 4 (depends on 1) The method of claim 1 further comprising: identifying that said UE does not have unicast high speed data transmission and reception; and based on said identifying and said determining, activating a power optimization procedure in order to reduce power consumption of the UE. ### Claim 5 (depends on 1) The method of claim 1 wherein the power optimization procedure lowers a clock rate of at least one hardware component of the UE. ### Claim 6 (depends on 1) The method of claim 1 wherein the power optimization procedure temporarily shuts down a communication bus between hardware of the UE. ### Claim 7 (depends on 6) The method of claim 6 wherein the communication bus is between a modem chip set and an application chip set. ### Claim 8 (depends on 1) The method of claim 1 wherein said processor device is a modem chip set. ### Claim 9 (depends on 1) The method of claim 1 wherein said activating is activated by an application chip set. ### Claim 10 An apparatus for wireless communication, comprising: means for determining that a User Equipment (UE) is in idle mode and receiving eMBMS (evolved Multimedia Broadcast and Multicast Service); and based on said determining, means for activating an optimization procedure in order to reduce power consumption of the UE. ### Claim 11 (depends on 10) The apparatus of claim 10 wherein the power optimization procedure is at least one of: a deep sleep; a light sleep; or a micro sleep. ### Claim 12 (depends on 10) The apparatus of claim 10 wherein the power optimization procedure is a multiple level hardware shut down comprising: a deep sleep; a light sleep; and a micro sleep. ### Claim 13 (depends on 10) The apparatus of claim 10 further comprising: means for identifying that said UE does not have unicast high speed data transmission and reception; and based on said identifying and said determining, activating a power optimization procedure in order to reduce power consumption of the UE. ### Claim 14 (depends on 10) The apparatus of claim 10 wherein the power optimization procedure lowers a clock rate of at least some hardware of the UE. ### Claim 15 (depends on 10) The apparatus of claim 10 wherein the power optimization procedure temporarily shuts down a communication bus between hardware of the UE. ### Claim 16 (depends on 15) The apparatus of claim 15 wherein the communication bus is between a modem chip set and an application chip set. ### Claim 17 (depends on 10) The apparatus of claim 10 wherein means for determining is a modem chip set. ### Claim 18 (depends on 10) The apparatus of claim 10 wherein said means for activating is an application chip set. ### Claim 19 A non-transitory computer-readable medium having program code stored thereon, wherein the program code, when executed by a computer, causes the computer to: determine that a User Equipment (UE) is in idle mode and receiving eMBMS (evolved Multimedia Broadcast and Multicast Service); and based on said determination, activate a power optimization procedure in order to reduce power consumption of the UE. ### Claim 20 (depends on 19) The non-transitory computer-readable medium of claim 19 wherein the power optimization procedure is at least one of: a deep sleep; a light sleep; or a micro sleep. ### Claim 21 (depends on 19) The non-transitory computer-readable medium of claim 19 wherein the power optimization procedure is a multiple level hardware shut down comprising: a deep sleep; a light sleep; and a micro sleep. ### Claim 22 (depends on 19) The non-transitory computer-readable medium of claim 19 further comprising program code causing the computer to: identify that said UE does not have unicast high speed data transmission and reception; and based on said identifying and said determining, activate a power optimization procedure in order to reduce power consumption of the UE. ### Claim 23 (depends on 19) The non-transitory computer-readable medium of claim 19 wherein the power optimization procedure lowers a clock rate of at least some hardware of the UE. ### Claim 24 (depends on 19) The non-transitory computer-readable medium of claim 19 wherein the power optimization procedure temporarily shuts down a communication bus between hardware of the UE. ### Claim 25 An apparatus configured for wireless communication, comprising: at least one processor;
